The National Republican Congressional Committee is targeting vulnerable House Democrats on the issue of impeaching President Donald Trump, Roll Call is reporting.

The NRCC is launching a digital ad campaign on Friday designed to pin down where certain Democrats stand on impeachment. According to Roll Call, the ads are the latest sign the GOP will attempt to tie vulnerable Democratic lawmakers to their more liberal colleagues.

One ad viewed by Roll Call showed Rep. Rashida Tlaib, D-Mich., and her prediction that Democrats will impeach Trump. The ad compared it with House Speaker Nancy Pelosi, D-Calif., saying he is “not worth it.” The ad then notes: “Democrats are split on baseless impeachment talks.”

The 12-second ads, which will run on Facebook in 55 districts, urge viewers to call a particular Democratic lawmaker to see where he or she stands on the issue.

“The socialist Democrats in Congress need to definitively state if they will stand up to the baseless attempts to impeach our president or if they will once again roll over for the extremists running their caucus,” said Rep. Tom Emmer, R-Minn., the NRCC chairman.
